/**
 * \def MBEDTLS_ECP_RESTARTABLE
 *
 * Enable "non-blocking" ECC operations that can return early and be resumed.
 *
 * This allows various functions to pause by returning
 * #MBEDTLS_ERR_ECP_IN_PROGRESS (or, for functions in the SSL module,
 * #MBEDTLS_ERR_SSL_CRYPTO_IN_PROGRESS) and then be called later again in
 * order to further progress and eventually complete their operation. This is
 * controlled through mbedtls_ecp_set_max_ops() which limits the maximum
 * number of ECC operations a function may perform before pausing; see
 * mbedtls_ecp_set_max_ops() for more information.
 *
 * This is useful in non-threaded environments if you want to avoid blocking
 * for too long on ECC (and, hence, X.509 or SSL/TLS) operations.
 *
 * This option:
 * - Adds xxx_restartable() variants of existing operations in the
 *   following modules, with corresponding restart context types:
 *   - ECP (for Short Weierstrass curves only): scalar multiplication (mul),
 *     linear combination (muladd);
 *   - ECDSA: signature generation & verification;
 *   - PK: signature generation & verification;
 *   - X509: certificate chain verification.
 * - Adds mbedtls_ecdh_enable_restart() in the ECDH module.
 * - Changes the behaviour of TLS 1.2 clients (not servers) when using the
 *   ECDHE-ECDSA key exchange (not other key exchanges) to make all ECC
 *   computations restartable:
 *   - ECDH operations from the key exchange, only for Short Weierstrass
 *     curves, only when MBEDTLS_USE_PSA_CRYPTO is not enabled.
 *   - verification of the server's key exchange signature;
 *   - verification of the server's certificate chain;
 *   - generation of the client's signature if client authentication is used,
 *     with an ECC key/certificate.
 *
 * \note  In the cases above, the usual SSL/TLS functions, such as
 *        mbedtls_ssl_handshake(), can now return
 *        MBEDTLS_ERR_SSL_CRYPTO_IN_PROGRESS.
 *
 * \note  This option only works with the default software implementation of
 *        elliptic curve functionality. It is incompatible with
 *        MBEDTLS_ECP_ALT, MBEDTLS_ECDH_XXX_ALT, MBEDTLS_ECDSA_XXX_ALT.
 *
 * Requires: MBEDTLS_ECP_C
 *

 * no difference, since all library functions can work with either format,
